I have deployed the script successfully but I noticed an issue when trying to update lead category.

Any ideas ?

Error:

Category matching query does not exist. Request Method: POST Request URL: http://127.0.0.1:8000/leads/1/category/ Django Version: 3.1.4 Exception Type: DoesNotExist Exception Value: Category matching query does not exist.

I've followed this tutorial to the last until the project is deployed where my issue arises. After deploying the project with DEBUG=FALSE, I get a Server Error (500) when I login. I then changed the debug setting to true so I can see the error message and it says OperationalError at /login/ no such table: leads_user. I viewed the database schema on my terminal and the table leads_user is present. Running migrations also doesn't solve it.

I finally tried logging in through your deployed project(https://crm.justdjango.com/) and I got a Server Error (500) so I'm assuming this is a problem a lot have faced. Anyone know what the fix is?

Hey Matthew I learn about your Youtube Video "Getting Started with Django". If i make the User Model with AbstractUser i never can login in my admin.

• I registrated the leads app in my Settings.
• I testet the config with and without AUTH_USER_MODEL = 'leads.User'

but it never works. What i make false?

# leads/model.py
from django.db import models
from django.contrib.auth.models import AbstractUser


class User(AbstractUser):
    pass

class Lead (models.Model):
    first_name = models.CharField(max_length=50) 
    last_name = models.CharField(max_length=50) 
    age = models.IntegerField(default=0) 
    agent = models.ForeignKey("Agent", on_delete=models.CASCADE) 

    def __str__(self):
        return f"{self.first_name} {self.last_name}"

class Agent(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    first_name = models.CharField(max_length=20)
    last_name = models.CharField(max_length=20)

    def __str__(self):
        return self.user.email

# leads/admin.py
from django.contrib import admin
from .models import User, Lead, Agent

class LeadAdmin(admin.ModelAdmin):
    model = Lead
    list_display = ('first_name', 'last_name', 'age', 'agent')

admin.site.register(User)
admin.site.register(Lead, LeadAdmin)
admin.site.register(Agent)

The current version of django-tailwind (3.1.1) package builds styles.css into this folder:

theme/static/css/dist/styles.css

The previous version used in the video (Intermediate Django - Lesson 19.TailwindCSS Improvements) builds into this one:

theme/static/css/styles.css

So, after deploying it into production you'll get such an error (fullscreen): And Server Error (500) on the prod.

Solution: Fix a link to styles.css inside templates/base.html to be this:

<link  href="{% static 'css/dist/styles.css' %}" rel="stylesheet">

p.s. I also had theme/static/css/dist/styles.css missing from a corresponding git commit at first, because it had turned out to be ignored by .gitignore.

The solution: Add line !/theme/static/css/dist to .gitignore

The form of the LeadCreateView is bugged.

It provides access to all the agents, including those from other organizations (created by other organizer users).

fullscreen

It's impossible to load a profile picture while creating a new lead.

The reason: form attribute enctype="multipart/form-data" is missing inside the lead_create.html.

Everything in the application from the tutorial so far (about to get into deployment) works perfectly except for UpdateAgentView. I've copy/pasted straight from this GitHub, and it still won't update the information for the agents. The form just goes back to agent-list with no changes on the front end, and no changes in the Agent or User table.

I've seen a few others post about this same issue on the YouTube video.

With that being said, what an amazing tutorial, and I've very appreciative of your work!

My best, Michael
